1. Introduction

I-7531 / I-7531-UT is a CAN repeater used to establish a physical coupling of two or more segments of a CAN bus system. User can implement tree or star topologies as well as for long drop lines with I-7531 / I-7531-UT. Connecting via I-7531 / I-7531-UT , the division of a CAN system into several subsystems increases the maximum number of bus nodes.

Figure1. Application of I-7531 / I-7531-UT

I-7531 / I-7531-UT is an optically isolated CAN repeater which provides 2500 V

rms

optical isolation allowing you to separate and protect critical segments of the system from the rest of the CAN network. And its galvanic isolation isolates both CAN segments from each other as well as from the power supply. The CAN connection of I-7531 is by terminal blocks. A power supply of 10 ~ 30 VDC is required. I-7531 / I-7531-UT is housed in a rugged DIN-Rail mountable box, making it easy to install in an industrial cabinet. Therefore, I-7531 / I-7531-UT can be used in CANopen, DeviceNet and generic ISO 11898-2 standard.

1.1 Features

 High speed  Removable terminal block & Mountable on DIN Rail  Bus pins protected against transients in an industrial environment  No disturbance of the bus lines with an un-powered node  Transmit data (TxD) dominant time-out function prevents the output drivers from driving

a permanent dominant state

 A thermal protection circuit is integrated to prevent the transceiver from damage if the

junction temperature exceeds thermal shutdown level
